DLM2000 Mixed Signal Oscilloscopes

The DLM2000 is a bench-top oscilloscope for electronic design or debug. It's ergonomic and easy to use, and packed with features. With bandwidths from 200 to 500 MHz and memory from up to 250 Mpoints, you can be certain there is a DLM2000 to meet your application and budget. With the DLM2000's industry first “flexible MSO input”, you can choose to activate channel four as an analog input, or use it to acquire 8 bits of logic instead. Modern electronics include analog and digital circuitry—and the DLM2000’s flexible MSO input lets you measure both, including mixed signal triggers and decoding of parallel or serial bit patterns. Options available include functionality for CAN, CAN FD, LIN, SENT, UART, I2C, SPI, PSI5 and CXPI bus analysis, and power supply analysis.

Compact & intuitive operation

Easy-to-Use & Easy-to-See

Easy to use. Portrait body + large screen makes display easy to see.

We elevated the large (8.4-inch) LCD screen up into the line of sight. Also, the portrait format saves space on the desk or test bench. A compact "personal oscilloscope" designed for easy viewing and ease of use.

Signal Observation on 4 channels or more...

Switch between analog and logic channels

Flexible MSO input

Four channels is not sufficient to view the functioning of digital control circuits. The DLM2000 series converts 4 ch of analog input to 8-bit logic, and functions as a 3 ch analog + 8-bit logic MSO (mixed signal oscilloscope).

4 ch analog

3 ch analog + 8-bit logic

The performance of up to 11 inputs by converting to logic

Using logic input, up to 11 input signals can be observed simultaneously as 3 ch of analog and 8-bit logic. It is not only possible to use logic input for observation of data and control signals, or as a trigger source, but also for logic
input analysis of I2C and SPI serial busses.

Note:The /M1, /M2, /M3 memory expansion options are only available on 4ch models. The /M1S option is only available on 2ch models.

Large capacity memory up to 250 Mpoints

Long memory is necessary to keep high speed sample rate in long term measurement.

Measuring time = Memory length/Sample rate

If 250 Mpoints (Memory expansion option /M3) is installed, Max. 0.2 sec waveform can be captured even at 1.25 GS/s sample rate when taking 2 ch measurements in Single mode.

History function - Automatically save previously captured waveform

With the DLM2000 series, up to 50000 previously captured waveforms can be saved in the acquisition memory. With theHistory function, you can display just one or all of the previously captured waveforms (history waveforms) on screen. You can also perform cursor measurement, computation, and other operations on history waveforms. Using the History function, you can analyze rarely-occurring abnormal signals.

Trigger function capturing combined analog/digital waveforms

The DLM2000 series comes with a variety of easy-to-configure triggers combining analog and logic inputs such as edge, enhanced, and B triggers.

Trigger Function Example

A to B(n) Trigger:
Trigger on the 7th edge of signal on B. This is effective for measurements with shifted timing, such as non-standard video signal vertical/horizontal periods or motor reference position pulses and drive pulses.

Serial Pattern Trigger (user defined):
Trigger on an arbitrarily set pattern of up to 128 bits. This is effective for detecting ID/Data and other portions of proprietary communication formats.

Dual Bus Trigger:
Trigger on a combination of CAN and LIN bus triggers. I2C + SPI bus triggers, and other combinations are possible.
Trigger when either LIN or CAN bus signal conditions become true.

Capture & Display Zoom and Search Functions

The DLM2000 series has two types of filters, one processed at the input circuit and one based on MATH functions. These filters are effective for rejecting unwanted signals, allowing observation of only the desired bandwidths.

Real Time Filters

Each channel has 14 low pass filters available from 8 kHz to 200 MHz. Waveforms of limited bandwidths are stored in internal memory.

Zooms into two different points - Waveform zoom and search functions

Zoom two locations simultaneously
Because the DLM2000 series lets you set zoom factors independently, you can display two zoomed waveforms with different time axis scales at the same time. Also, using the Auto Scroll function, you can automatically scroll waveforms captured in long memory and change the zoomed location. With Auto Scroll you can choose forward, backward, fast-forward, scroll speed, and other control options.

Large capacity memory gives you a variety of waveform search functions

Two types of waveform searching:
Normally, searching for data takes time and costs money, and long memory is useless without functions for extracting desired data from a large capacity memory. That's why the DLM2000 series does not simply offer long memory, it also provides powerful waveform search functions.

Searching for data in a single screen: the Zoom Search function
This function searches captured waveforms in the long memory and displays waveforms that meet the search criteria in the zoom area. The locations of the found waveforms are marked on screen

Searching for history waveforms: the History Search Function
Criteria can be specified for extracting desired waveforms from up to 50,000 previously captured waveforms.

Searching for waveforms in zones created by moving measured waveforms up/down/left/right.

Search for waveforms that pass through/do not pass through a rectangular zone placed on screen.

Useful Functions - Fastest and most capable analysis

Display trends of peak-to-peak or pulse width per cycle

Measure function and statistics
Twenty-eight waveform parameters are included such as: maximum, minimum, peak-to-peak, pulse width, period, frequency, rise/fall time, and duty ratio. Automated measurement can be performed using up to 20 of these waveform parameters. Also, waveform parameters can be measured repeatedly, and the statistical values displayed (mean, maximum, minimum, standard deviation, etc.).

Trend and histogram displays
Waveform parameters such as period, pulse width, and amplitude can be measured repeatedly and displayed in graphs. In a single screen you can observe period-by-period fluctuations, compute amplitudes every screen using multiple waveforms, and display amplitudes as trends. You can also display histograms referencing the voltage or time axis using values from repeated automated measurement of waveform parameters.

Trend display of waveform parameters

Histogram display using the time axis

Measures voltage/time differences automatically - Cursor Measurement -
Cursors can be placed on the displayed waveform from signal data, and various measurement values at the intersection of the cursor and waveform can be displayed. There are six types of cursor; ΔT, ΔV, ΔT& ΔV, Marker, Degree Cursor.

Simultaneous level and with the

ΔT&ΔV cursor

Analyzes Frequency Spectrums
- FFT Analysis -
Up to 2 FFT analyses can be performed simultaneously. FFT can be performed on computed waveforms in addition to the actual waveforms on CH1 to CH4. Analysis can be performed of the frequency components of waveforms filtered for limited bandwidth, of frequency for changes in period of rotary objects, and other phenomena.

Keeps waveforms with one push
By pressing the SNAPSHOT key to the lower right of the screen, you can freeze a white trace of the currently displayed waveform on the screen. You can press the key repeatedly and conveniently leave traces for comparing multiple waveforms. Also, snapshot data recorded on screen can be saved or loaded as files, and can be recalled for use as reference waveforms when making comparisons.

Displays stored files in thumbnail format
Thumbnails of waveform data, waveform image data, and Wave-Zone files can be displayed. The image and file names are shown so that you can view screen image contents while copying or deleting files. A file can be enlarged to confirm the data.

Has a GO/NO-GO function
GO/NO-GO can be determined using trigger conditions, zone waveforms, measurement parameters, and other criteria. For NO-GO, actions can be carried out at the same time such as sounding a buzzer, saving the current waveform, or sending notification to a designated e-mail address. Waveforms in which an abnormality occurred can be saved for confirmation and analysis of the phenomena at a later time.

Can check functions with graphical online help
You can view detailed graphical explanations of the oscilloscope's functions by pressing the "?" key in the lower left of the screen. This lets you get help on functions and operations on screen without having to consult the user's manual.
